lord1234:umm...why not shop ebay?
I did.
I now have a complete, fairly high-performance US Divers reg stuck together from various components from eBay, that cost me less than a new entry-level reg: SE2 first stage/Pro Diver second stage/recent model Aqua Lung Octo/gauge console-computer from one of my old regs. The only piece that was a waste was the Pro Diver first stage because I learned to my dismay that it was one of the few modern USD models that are no longer supported.
If you know what you're doing you can take that mix & match approach. Otherwise I say definitely look at eBay, specifically for used reg setups by reputable brands. For the sake of longtime support, plus that they've got excellent reps as bulletproof and high performance regs, I'd stick with USD and Scubapro. Old USD regs seem to go for less than Scubapros; I've seen plenty of '80s and early '90s era Conshelfs go for less than $100 for a first, second, octo, and gauges. Beware of regs that are too old, though, ie those first stages that have wing-type yoke screws and not enough ports. Either way, do your research, no matter where or how you buy your gear. Good luck!
Oh, and if no one mentioned it already, avoid used Dacor regs like the plague. eBay is infested with loads of old Dacor regs for crazy cheap--people undoubtedly unloading them because they've found that they can't get annual, or ANY, service for them anymore. They're essentially scuba-gear-shaped paperweights. Don't bite...er buy it.
